Description
Technical Field
The present invention relates to the field of virtual machine technologies, and in particular, to a method, an apparatus, a device, and a medium for data backup of a virtual machine.
Background
The data protection is carried out by utilizing the virtual machine, and the data protection method is a data protection mode which can recover original production data in a short time and ensure normal operation of user services after a data disaster occurs. In the prior art, in the process of backing up data of a virtual machine, the data is usually protected by fully backing up the data of the virtual machine in real time. That is, the virtual machine needs to write the change data generated by the virtual machine into the source storage pool of the virtual machine during the operation process, and also needs to backup the change data to the backup storage pool. In this case, the virtual machine must wait until the current time change data is written into the backup storage pool before the virtual machine can perform the next data operation. Obviously, during the process of writing the change data into the backup storage pool by the virtual machine, because the change data is written into the backup storage pool through an external transmission network, the writing time required by the virtual machine when writing the change data into the backup storage pool is much longer than the time required by writing the change data into the virtual machine source storage pool, thereby causing the virtual machine to consume a large amount of backup time when performing data backup. At present, no effective solution exists for the technical problem.
Therefore, how to reduce the backup time required in the process of performing data backup on a virtual machine is a technical problem to be solved urgently by those skilled in the art.

before starting a target virtual machine, copying all disk files of the target virtual machine to a backup storage pool;
when the target virtual machine is started, pausing the target virtual machine and creating a target bitmap file in the target virtual machine;
restoring the target virtual machine and storing the change data in the target virtual machine to the target bitmap file;
and storing the change data in the target virtual machine to a source storage pool of the target virtual machine in real time, and backing up the change data stored in the target bitmap file to the backup storage pool according to a preset period.
Preferably, the process of copying all the disk files of the target virtual machine to the backup storage pool includes:
and copying all snapshot files and top-level files in the target virtual machine to the backup storage pool.
Preferably, the preset period is a user-defined time period.

Preferably, the target virtual machine is specifically a QEMU-KVM virtual machine.
Preferably, the method further comprises the following steps:
and if the source storage pool of the target virtual machine is damaged in the running process of the target virtual machine, switching the target virtual machine to the standby storage pool to run.
Correspondingly, the invention also discloses a data backup device of the virtual machine, which comprises:
the file copying module is used for copying all disk files of the target virtual machine to a backup storage pool before starting the target virtual machine;
the file creating module is used for pausing the target virtual machine and creating a target bitmap file in the target virtual machine when the target virtual machine is started;
the virtual machine starting module is used for recovering the target virtual machine and storing the change data in the target virtual machine to the target bitmap file;
and the data backup module is used for storing the change data in the target virtual machine to a source storage pool of the target virtual machine in real time and backing up the change data stored in the target bitmap file to the backup storage pool according to a preset period.
Correspondingly, the invention also discloses a data backup device of the virtual machine, which comprises:
a memory for storing a computer program;
a processor for implementing the steps of a data backup method of a virtual machine as disclosed in the foregoing when executing the computer program.
Accordingly, the present invention also discloses a computer readable storage medium, on which a computer program is stored, which, when being executed by a processor, implements the steps of the data backup method of a virtual machine as disclosed in the foregoing.
It can be seen that, in the virtual machine data backup method provided by the present invention, first, before starting the target virtual machine, all disk files in the target virtual machine are copied to the backup storage pool; then, when the target virtual machine is started, suspending the target virtual machine to ensure the consistency of the data in the source storage pool and the backup storage pool of the target virtual machine, and creating a target bitmap file in the target virtual machine; then, restoring the target virtual machine, and storing the change data of the target virtual machine in the running process to the target bitmap file; and finally, storing the change data in the target virtual machine to a source storage pool of the target virtual machine in real time, and backing up the change data stored in the target bitmap file to a backup storage pool according to a preset period. In the invention, because the changed data of the target virtual machine in the operation process is backed up to the backup storage pool from the target bitmap file according to the preset period, the target virtual machine does not need to wait until the backup storage pool finishes backing up the changed data at the previous moment, and then can start the data backup at the next moment. Obviously, compared with the prior art, the time required by the target virtual machine to wait when the changed data is backed up to the source storage pool is reduced, so that the backup time required by the target virtual machine in the data backup process can be significantly reduced.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a data backup method of a virtual machine according to an embodiment of the present invention, where the data backup method includes:
step S11: before starting the target virtual machine, copying all disk files of the target virtual machine to a backup storage pool;
step S12: when the target virtual machine is started, pausing the target virtual machine, and creating a target bitmap file in the target virtual machine;
step S13: restoring the target virtual machine and storing the change data in the target virtual machine to a target bitmap file;
step S14: and storing the change data in the target virtual machine to a source storage pool of the target virtual machine in real time, and backing up the change data stored in the target bitmap file to a backup storage pool according to a preset period.
In this embodiment, a data backup method for a virtual machine is provided, by which backup time required in a process of backing up data of a target virtual machine can be relatively shortened. Specifically, firstly, before starting the target virtual machine, copying all disk files in the target virtual machine to the backup storage pool, and suspending the target virtual machine when the target virtual machine is started, that is, before the target virtual machine performs a backup operation, the target virtual machine is always in a suspended state, thereby ensuring that the source storage pool of the target virtual machine is consistent with the data in the backup storage pool.
And when the target virtual machine is in a suspended state, creating a target bitmap file in the target virtual machine so as to store the change data generated by the target virtual machine in the running process by using the target bitmap file. And then, restoring the target virtual machine to enable the target virtual machine to enter a normal operation state, storing the change data in the target virtual machine into the target bitmap file after the target virtual machine enters the normal operation state, simultaneously storing the change data in the target virtual machine into a source storage pool of the target virtual machine in real time, and backing up the data stored in the target bitmap file to a backup storage pool according to a preset period.
Assuming that the preset period is 5 seconds, the target virtual machine stores the change data in the running process in the target bitmap file and the source storage pool of the target virtual machine in real time within a period from the start to the running of 5 seconds, and the target virtual machine backs up the data stored in the target bitmap file to the backup storage pool when running to the 6 th second. That is, the target virtual machine will write the changed data of the target virtual machine to the backup storage pool once within a period of 5 seconds from the start of the start to the operation of the target virtual machine. And in the next preset period, namely when the target virtual machine runs to the 11 th second, the target bitmap file stores the change data generated by the target virtual machine in the running process from the 5 th second to the 10 th second, and at the moment, the target virtual machine backs up the change data generated by the target virtual machine stored in the target bitmap file in the running process from the 5 th second to the 10 th second into the backup storage pool.
Obviously, compared with the prior art that the target virtual machine is required to completely transfer the change data generated at the current time to the backup storage pool, for the data backup at the next moment, by the method provided by the embodiment, since the target virtual machine stores the change data of the target virtual machine in the running process to the source storage pool in real time, and write the change data generated by the target virtual machine in the preset period into the backup storage pool at one time according to the preset period, this reduces the waiting time required by the target virtual machine to backup the changed data generated during the operation to the source storage pool, therefore, the backup time required by the target virtual machine in the data backup process can be obviously reduced, and the data backup speed of the target virtual machine in the data backup process can be improved. Obviously, the problem that the running speed of the target virtual machine is slowed down due to the real-time backup of the target virtual machine in the prior art can be solved through the backup mode.
As can be seen, in the virtual machine data backup method provided in this embodiment, first, before starting the target virtual machine, all disk files in the target virtual machine are copied to the backup storage pool; then, when the target virtual machine is started, suspending the target virtual machine to ensure the consistency of the data in the source storage pool and the backup storage pool of the target virtual machine, and creating a target bitmap file in the target virtual machine; then, restoring the target virtual machine, and storing the change data of the target virtual machine in the running process to the target bitmap file; and finally, storing the change data in the target virtual machine to a source storage pool of the target virtual machine in real time, and backing up the change data stored in the target bitmap file to a backup storage pool according to a preset period. In this embodiment, because the changed data of the target virtual machine during the operation process is backed up to the backup storage pool from the target bitmap file according to the preset period, the target virtual machine does not need to wait until the backup storage pool finishes backing up the changed data at the previous time, and then can start the data backup at the next time. Obviously, compared with the prior art, the time required by the target virtual machine to wait when the changed data is backed up to the source storage pool is reduced, so that the backup time required by the target virtual machine in the data backup process can be significantly reduced.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, specifically, the steps are as follows: the process of copying all disk files of the target virtual machine to the backup storage pool comprises the following steps:
and copying all snapshot files and top-level files in the target virtual machine to the backup storage pool.
In this embodiment, in order to copy all data in the target virtual machine to the backup storage pool, all snapshot files and top-level files in the target virtual machine are copied to the backup storage pool, because the disk files in the target virtual machine can be roughly divided into two types, that is, one type is a snapshot file for recording state information of the target virtual machine at a certain time, and the other type is a top-level file for storing when the overall architecture of the target virtual machine is built. Therefore, in this embodiment, in the process of copying all the disk files of the target virtual machine to the backup storage pool, all the snapshot files and the top-level files in the target virtual machine are copied to the backup storage pool, thereby ensuring the integrity in the process of copying all the disk files to the backup storage pool.
Therefore, by the technical scheme provided by the embodiment, the overall reliability in the process of copying the disk file of the target virtual machine can be further improved.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, and specifically, the preset period is a time period defined by a user.
Specifically, in this embodiment, the preset period is set according to a time period defined by a user, that is, in the process of backing up the data stored in the target bitmap file to the backup storage pool, the data stored in the target bitmap file may be backed up to the backup storage pool according to the time period defined by the user. It is conceivable that, by such a setting manner, the user can adaptively adjust the preset period according to different actual situations, so as to adapt to changes of application scenarios.
Therefore, by the technical scheme provided by the embodiment, the user experience of the user in the data backup process of the target virtual machine can be further improved.
Based on the above embodiments, this embodiment further describes and optimizes the technical solution, specifically, the steps are as follows: after the process of backing up the change data stored in the target bitmap file to the backup storage pool according to the preset period, the method further comprises the following steps:
the changed data backed up to the backup storage pool is deleted from the target bitmap file.
It can be understood that, during the process of storing the change data in the target virtual machine into the target bitmap file, all the change data of the target virtual machine during the operation process is stored in the target bitmap file, and when the change data stored in the target bitmap file is backed up into the backup storage pool according to the preset period, the part of data stored into the backup storage pool is equivalent to redundant data in the target bitmap file, in this case, the part of data can be deleted, that is, the change data backed up into the backup storage pool is deleted from the target bitmap file. Therefore, the occupation amount of the target bitmap file on the storage space can be relatively reduced, and the overall backup efficiency of the target virtual machine in the data backup process can be further improved.
Therefore, by the technical scheme provided by the embodiment, the storage space required by the target bitmap file can be further reduced.
Based on the foregoing embodiments, this embodiment further describes and optimizes the technical solution, and as a preferred implementation, the target virtual machine is specifically a QEMU-KVM virtual machine.
Specifically, the target Virtual Machine may be set as a QEMU-KVM (Kernel-based Virtual Machine) Virtual Machine. In the QEMU-KVM virtual machine, the KVM virtual machine runs in the kernel space, and the QEMU runs in the user space, which can actually simulate and create and manage various virtual hardware, so the QEMU-KVM virtual machine has a faster running speed compared with other virtual machines, and the QEMU-KVM virtual machine is widely applied in actual operation, so when the target virtual machine is set as the QEMU-KVM virtual machine, the data backup speed of the target virtual machine in the data backup process can be relatively increased, and the universality of the virtual machine data backup method provided by the application in actual application can also be relatively increased.
Based on the foregoing embodiment, this embodiment further describes and optimizes the technical solution, and specifically, the data backup method for a virtual machine further includes:
and if the source storage pool of the target virtual machine is damaged in the running process of the target virtual machine, switching the target virtual machine to the standby storage pool to run.
It can be understood that, in practical applications, the target virtual machine inevitably encounters unexpected situations during the operation, such as: the source storage pool of the target virtual machine is damaged, so that the normal use of the target virtual machine by people is influenced.
In this case, the target virtual machine may be switched to the standby storage pool to operate, and since the data stored in the standby storage pool is consistent with the data in the source storage pool of the target virtual machine, when the target virtual machine is switched to the standby storage pool to operate, not only the normal use of the target virtual machine is not affected, but also economic loss caused by the interruption of the operation of the target virtual machine to a user can be avoided.
